Arch Linux User Repository

AFAIK, the build prefix is embedded in /usr/lib/julia/sys.so. If I edit it with sed, /usr/bin/julia will raise segmentation fault. I don't know is there a proper way to edit this file now.

@xia0er There is already a bug report about the prefix, see https://bugs.archlinux.org/task/63255.

Abount openmp, should it be a dependency of julia-arpack?
I can pass most of the tests in the check() function with about 5 tests skipped.
So I think julia-mkl doesn't need openmp itself.

Should openmp be added to the package dependencies? I am getting an error:

julia: symbol lookup error: /opt/intel/mkl/lib/intel64/libmkl_intel_thread.so: undefined symbol: __kmpc_global_thread_num

when loading julia packages that depend on mkl, for example, Arpack, which is fixed by installing openmp.

@petronny, thanks for the response! As I understand it is mostly cosmetic, I can certainly wait for it to be resolved upstream.

@xia0er Actually this bug also happens in the official julia package.

You can find /build/julia/src/julia-1.1.1/ in the stacktrace which is the build path in chroot since it is build with extra-x86_64-build.

I provide a pre-built binary of this package which is also built with extra-x86_64-build in arch4edu. It will give the similar stacktrace like the official one. You can use it for now. I'll contact with the maintainer of julia and see what we can do about the build path.

Is there a way to fix the fact that where julia is being built is embedded in the installed files? For example, when I got permission denied error for a log file, the error message reports the Operations.jl is at /home/xia0er/.cache/yay/julia-mkl/src/julia-1.1.1/usr/share/julia/stdlib/v1.1/Pkg/src/Operations.jl (where julia-mkl is being built by yay), even though I started julia after installing julia-mkl and can verify that Operations.jl is at /usr/share/julia/stdlib/v1.1/Pkg/src/Operations.jl. Granted this is mostly cosmetic as far as I can see.

Hi, I just dropped julia-mkl-docs.
I think it's same with julia-docs. Please leave a comment if it's not. I will add it back.

maybe help https://gist.github.com/specter119/e7a86a202b0ecb77334cb5c437085e5e

Hi.

Using

1) git clone git://github.com/JuliaLang/julia.git
2) cd julia & git checkout v0.6.0
3) patch -p1 -i ../julia-libunwind-version.patch

and following the idea of your PKGBUILD I could compile and install julia
with MKL.

Thanks.

I have deleted all the contents of the tmp directory and the error remains the same. Anyway, thanks for the help.
Cheers !
